Hi Ray,
Good to hear from you again.
Enjoy your retirement.
Congrats on the quitting smoking.
I'm about to do it again. I'm also a COPD guy.
REMEMBER...There's no such things as "just one cigarette" for a long-time smoker.
When I stopped last year, for 3 months, (the longest stop in 52 years!) I decided to have "just one".
One is too many...and a thousand is not enough.
Take it a day at a time.
I'll put you in my prayers.

Mick
